This is one of the few companies that gives you a lumen rating, and ACTUALLY MEANS IT! I'm just so shocked, because I like to review bicycle lights, and have come across quite a few who advertise the lumen rating on their lights as far in excess of what they really are! Alright, maybe I'm wrong, but when I tested this light on bright, against a light boasting 960 lumens, (also on bright [basically as bright as both lights could go]) This "Serfas True 750" blew the other light away! The thing is, I LIKE the brand of light I put it up against, and was both surprised, and disappointed that the 960 lumen light lost! Oh, for reference, this was the light " Night Provisionβ„’ ULTRA BRIGHT BX-960 USB Rechargeable Bike LightHeadlight & Flashlight LED 960 Lumen ". This is the first "Serfas" light I've ever owned, and due to it performing unexpectedly well, I think I'll try a few more lights from "Serfas"! Now, I want to give you some technical details of the light. It ALWAYS starts off (when you first turn it on) in 'Turbo' mode, (since it [unfortunately] has no 'mode memory'). Then it goes high, medium, and low, in that order. If you press the button again, it goes back to 'Turbo'mode. To turn it off, you need to hold down the power button for 2 seconds. It fades out, but comes on like flipping a switch on your bedroom light. However, to get it into the flashing mode (which is like a car with a fast turn signal) you have to hold down the power button to turn off the light, then continue holding the power button down, and it will begin to blink. OR, if you just want to turn on the blink WITHOUT turning on the light, just press the power button and hold it down for 2 seconds. However, this light has something I've never seen before! If you just hold down the power button from completely off, it will flash, but if you turn the flash off, and do it again, it will come on with a solid light! I guess it alternates between the two modes! Weird. Well, I'm not used to it, anyway. As for the measurements, they are :4.5" (114.3 mm) Long x 2" (50.8 mm) Wide x 1.5" (38.1 mm) High/Deep. I intend to add a video when I get the chance to (because I want to share its performance with you) and hopefully, I will soon! (UPDATE 11-22-2016) I also wished to mention, that when I looked at the picture on the main website, The front of the light looked beige. Actually, the piece on the front of the light is more of a gold color, and the gold coloring is metal. The rest of the light (the black part) is plastic. Also, the mini-USB port(for charging) is on the bottom, (in the gold metal area) under a rubber flap. I'll add some photos to show this. ### ⭐⭐⭐⭐ love it *by M***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on April 20, 2014* Hard to turn on sometimes and turns on blinking so I have to shut it off and back on to get the solid light. It's amazing as far as brightness, I have the 150 model too and the difference is unbelievable. When I need a light I reach for this one every time. I used this this light out camping and could see clear across a meadow and right into the forest. It is only suppose to be used on a bike, it needs to be in the wind to stay cooled down. Wish it would hold a charge longer. I would buy this again and would recommend it to a friend. I love this light. Only gave it 4 stars because to turn it on ya have to hold the button on for a bit and most of the time it turns on blinking on the first attempt to turn it on. ### ⭐⭐⭐⭐ Excellent system. Two recommendactions for the manufacturer *by K***N on Reviewed in the United States πŸ‡ΊπŸ‡Έ on March 18, 2016* Excellent system. Two recommendactions for the manufacturer. 1 Beef up the handle bar mount. It's the same size used in the smaller lighter headlight.2. Give it a blink mode like my older smaller versionDarn good light though. Don't leave home with out one. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fi/products/533084561-serfas-tsl-750-usb-headlight](https://www.desertcart.fi/products/533084561-serfas-tsl-750-usb-headlight) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-05-17*
